Gram-positive rods. Nonspore-forming.
On Columbia horse-blood agar its colonies are small, entire, non-pigmented and do
not produce an odour. Facultatively anaerobic. Grow at 45 ºC, not at 15 ºC.
Isolated from human sources. The habitat is unknown.
Undetermined.

Obligately heterofermentative (hexoses are fermented to lactic & acetic acid (ethanol),
and CO2 via the phosphogluconate pathway; pentoses are fermented to lactic & acetic
acid by the related pentose phosphate pathaway.
Positive results for glucose fermentation.
Negative results for arginine hydrolysis, catalase, esculin hydrolysis, gelatin liquefaction, nitrate reduction, oxidase, urease,
Voges-Proskauer, fermentation of: arabinose, D-arabitol, cellobiose, esculin, galactose, glycogen, lactose, mannitol, mannose,
melezitose, melibiose, raffinose, salicin, sorbitol, sucrose, trehalose and xylose.
Variable results for ribose fermentation and gas production from glucose fermentation.
